1. The synthesis of Grignard reagent is challenging. a) Draw the product that is expected to be formed if the Grignard reagent was in contact with water prior to the reaction with MgBr CO2? (2 pts) b) Circle the correct answer. In the reaction in 1 a), phenyl magnesium bromide acts as a (nucleophile/electrophile/base/acid). (1 pt) Consider the following reaction and circle the correct answer. In this reaction, phenyl magnesium bromide acts as a, Oo MgBr MgBr (nucleophile/electrophile/base/acid). (1 pt) coz I 3. What is incorrect about the product; benzoic acid that is obtained in today’s experiment? (2 pts) TOO MgBr C ooha) The product will produce a singlet around 11-12 1. Mg, ether ppm in NMR HCI, H2O b) The product will have a low solubility in water 2. CO2 c) The product will have a low solubility in ether d) The product will produce a broad peak around 2500 cm 1 – 3100 cm 1 in IR 4. Consider the following extraction scheme.
